The invention discloses a detection device and method for transverse swing displacement of a vertical shaft lifting steel wire rope. The detection device comprises a supporting frame, a longitudinal laser device, a longitudinal camera, a longitudinal light shield, a transverse laser device, a transverse camera, a transverse light shield and a signal processor. The supporting frame is fixed to a shaft frame at a shaft opening of a vertical lifting shaft. The transverse laser device and the longitudinal laser device are transversely and longitudinally arranged on the inner wall of the supporting frame respectively. The transverse camera and the longitudinal camera are arranged behind of the transverse laser device and the longitudinal laser device in the projection directions of the transverse laser device and the longitudinal laser device respectively. A projection image of the steel wire rope after being illuminated by each laser device on the inner wall of the supporting frame is photographed through the corresponding camera, and then the projection images are transmitted to the signal processor. The two orthometric laser devices are adopted to illuminate the steel wire rope, the projection image of the steel wire rope after being illuminated by each laser device is photographed through the corresponding camera, in this way, the transverse swing displacement amount in the X direction and in the Y direction of the steel wire rope along the cross section of the steel wire rope can be detected in real time, the detection accuracy is high, and reliability, convenience, fastness and wide practicability are achieved.
